15、magine 等后面作宾补的结构 to ben./adj.中的 to be 可以省略。I consider him(to be)lazy.我认为他懒。His mother found him(to be)a clever boy.他母亲发觉他是一个很聪明的孩子。(2)感官动词 see,hear,feel,watch,notice 等以及使役动词 let,make,have 后作宾补的动词不定式中的不定式符号 to 要省略，但变为被动语态时，to 必须保留。They made the boy go to bed early.他们让这个男孩早睡。The boy was made to go to
16、bed early.这个男孩被迫早睡。(3)but 作“除之外”讲时，其前有实义动词 do 的形式，but后的不定式须省去 to。We have nothing to do now but wait.我们现在除了等没有别的事可做。He has no choice but to accept the fact.除了接受这个事实他别无选择。(4)在并列结构中为了避免重复，可省去后面的不定式符号 to。It is impossible to laugh and(to)cry at the same time.同时又哭又笑是不可能的。(5)动词不定式中动词原形部分是否省略，主要看句子前面是否已出现过同
17、样的动词。如果句子前面出现过同样的动词，为了避免重复，句子后面的不定式常省略动词原形，而保留不定式符号 to。They may go if they wish to(go)如果他们想去，他们就可以去。Dont go till I tell you to.直到我让你去，你才可以去。(6)主语从句中有 do 的某种形式，后面不定式作表语，动词不定式标志 to 可以省略。All we can do is(to)wait for another twenty minutes.我们所能做的是再等 20 分钟。2简单句中的省略(1)感叹句中常省略主语和谓语。What a hot day(it is)！多热
18、的天啊！(2)在一些口语中可以省略某些句子成分。(Will you)Have a smoke？你抽烟吗？3并列句中的省略(1)如果主语不同，而谓语中的一部分相同，则省略谓语中相同的部分。John must have been playing football and Mary(must have been)doing her homework.约翰一定一直在踢球，而玛丽一定一直在做作业。(2)主语相同，谓语也相同，则二者都可以省略。His suggestion made John happy，but(his suggestion made)Mary angry.他的建议使约翰高兴，却使玛丽很生
19、气。(3)主语相同，而谓语不同，则可以省略主语。Danny gave up smoking for a while，but(he)soon returned to his old habit.丹尼戒了一阵子烟，可很快又开始抽烟了。4复合句中的省略(1)宾语从句中的省略在宾语从句中常省略连词 that，但当及物动词之后跟两个或两个以上的宾语从句时，只有第一个连词 that 可以省略。(2)状语从句中的省略当状语从句中的主语和主句的主语一致或从句主语为 it，并且从句谓语中有 be 动词时，常可以省略从句中的主语和 be 动词。此类状语从句中的省略有如下情况：在 as，before，till，wh
